C/2011 L4 is starting to become visible from the northern hemisphere. Anyone able to spot it yet? I'll give it a try tomorrow with if the weather holds.

We finally had the first clear night in two weeks here. I tried to spot it after sunset but had no luck. However I don't have anyplace to go that has a very good view to the western horizon. I also suspect that I might not get another chance as the clouds will probably return for another week or two

The sun was at -7° in the picture. And conditions couldn't be better, extremely dry air (-8°C and 35% relative humidity). My latitude is 60°. A bunch of other people tried to spot it from southern Norway last night, visually and photographically. None were successful.

The comet was successfully photographed last night from New Jersey (~40°N), but only just barely -- in the photo the comet was only a degree above the horizon!

So I'm guessing the sky becomes sufficiently dark when the sun is <~-10°. Last night from your location at 60°N the comet was 2° below the horizon at that time. But by Wednesday that will be to to +3°, and +10° by next week.

I looked yesterday. There were only a few clouds in the sky, which of course happened to park just above the western horizon. But I read one report from someone who saw the comet from Oslo yesterday. Then the comet was just 0.2 degrees above the horizon.

The forecast for tonight is cloudy and light snow, so unless it brightens to at least -30, I wont see it. But tomorrow, Wednesday, looks very promising, and then it should be obvious for the naked eye as well.

That view is so stunning, love the timelapse with the precipitation bands.

As luck would have it my skies completely cleared up a few hours before sunset, and I was able to spot the comet. It was much harder to see than I had guessed. In fact I was never was able to see it with unaided eyes; I had to use a spotting telescope, and my first visual sighting was when the sun was about 8° below the horizon (putting the comet about 6 degrees above). It was very easy to pick up with the DSLR camera though, using a 2-2.5 second exposure with ISO 800. I've upped the brightness/contrast slightly in the photos as well.
